10.
The magnetic field intensity vector of a plane wave is given by 
(x, y, z, t) = 10 sin (5000t + 0.004x + 30 
), where denotes unit vector in y direction the wave is propagating with a phase velocity.
(x, y, z, t) = 10 sin (5000t + 0.004x + 30 ), where denotes unit vector in y direction the wave is propagating with a phase velocity.Answer: Option
Explanation:
(x, y, z, t) = 10 sin (5000t + 0.004x + 30)
Wave is propagating in - ve direction, hence
v = - 1.25 x 107 m/sec.
